ProSeries mag help!

[pro45cal]

So I recently purchased the pro series sub compact 1911 .45 and I can't find any mags for her. I prefer to purchase the original mags not Wilson combat or pro mag that gun shops tell me to buy.. I found one on eBay from a 4516 model but I have no clue if its compatible, any idea if it is??

They would only use 1911 mags, the 4516 won't work. I believe S&W uses the Wilson mags, both my Pro Series came with them. But I prefer the Chip McCormick power mags myself actually.
